I need to back off of my original assertion, because I was wrong.  The
Python ssl module does use OpenSSL.  I didn't see it doing any imports,
so I assumed it was using something else.

However, it links to it statically, so there shouldn't be any DLL conflicts.

It is not generally possible to load multiple versions of a single DLL
in Windows.  The system loader will satisfy the externals from the
already loaded version.  You certainly can have multiple copies of a
statically linked library, but it's not clear to me how that would cause
any problems.

Then please be sure to cc the list.  And wouldn't it be easier just to
join the list until your issue is resolved?
